I'd appreciate some advice. Has anyone had experience of suspension stiffeners - spring assisters- rubber inserts into the rear suspension springs.

The car sags when hitched . The tow bar limit is 75 kg and I'm using a 60 Kg noseweight. I'm hoping the inserts will stop/ limit the sag.

|Do they work ? What are the problems ? I read that they can increase the chance of breaking a spring.

Many thanks.

Unless the car has an abnormally large rear overhang from back axle to towball that statement is a bit illogical. I wouldn't call the rear overhang of a Berlingo particularly large.

Three bags of cement weigh 75kg which is less than 60kg on the towball, so how can the back end of the car sag more with just 60kg on the towball, but not with 75kg in the boot?

The cement is in the boot so above the axel giving a downforce of 75kg. Putting 75kg on the towball which is 2 foot further back gives 75kg x the distance loading on the axel. much more load on the springs.
